Skały meta morficzne podłoża północno-wschodniej Polski (Sokółka)
Abstract
METAMORPHIC ROCKS OF SUBSTRATUM OF NORTHEASTERN POLAND (Sokółka)Among the metamorphic rocks, the author distinguishes rocks metamorphosed dynamically and regionally.To the former group belong the rocks of a tectonic breccia, appearing in a 13 m. thick horizon underneath sedimentary rocks in bore hole Sokółka 1. These latter are quartz sandstones, phyllites and phyllonites. Cataclasites appear chiefly in biotite gneisses and plagioclase-quartz biotite gneisses.The regionally metamorphosed sediments are much varied. Among them, following their arrangement in the bore-hole prosections, three groups of rocks have been distinguished: schists, gneisses and migmatites.The quartz-magnetite schists appear in bore-hole Sokółka 1 in the form or a thin, 5 cm. layer. Their composition comprises 53% quartz, 24% magnetite and 12% cummingtonite.The amphibole-epidote schists in bore hole Sokółka 1 contain, moreover, plagioclase abundantly.Downloads
